摘要
根据湿度应力场理论与温度应力场理论控制微分方程中存在的类比关系,通过参数转换,将求解湿度应力场问题转化为求解温度应力场问题。并利用ANSYS软件系统中的温度应力场分析功能,对地下开采中膨胀岩巷道遇水和地应力耦合作用问题进行了数值模拟。得到不同支护强度条件下的膨胀岩底板巷道围岩遇水作用后的应力和变形分布,并与无水作用情形作了对比分析。研究结果可为膨胀岩巷道围岩变形控制提供理论依据。
According to the analogical relation in the governing differential equations of the humidity-stress-field theory and temperature-stress-field theory, the problem of solving the humidity stress field is transformed into that of solving the temperature-stress-field by the change of parameters. So, the problem of the roadway in the swelling rock under the coupling function of water and ground stress can be solved by the analytical module of temperature stress field in software ANSYS. In the numerical simulation mentioned above, the different support pressures are taken into account and the stress distribution and deformation states of the roadway are analyzed under the floor in the action of water and are compared with that of non-water action. The research results provides scientific basis for the deformation control of the roadway in swelling rock.
